simplexml_load_string返回空白数组

Question

我正在使用第三方Web服务发布请求并通过使用php curl的soap获得响应。响应很好，但由于某种原因我无法解析响应。当我使用simplexml_load_string时给我空白。

我的代码是

// PHP cURL for https connection with auth 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_USERPWD, $soapUser.":".$soapPassword); // username and password - declared at the top of the doc 
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY); 
curl_setopt($ch, CURLOPT_TIMEOUT, 10); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 

// converting 
$response = curl_exec($ch);    
print_r($response); // when I print response it shows me the correct response with data. 
but when I am doing , 

$parser = simplexml_load_string($response2);   
print_r($parser); // it's giving SimpleXMLElement Object () 

标题是

$headers = array(
         "Content-type: text/xml;charset=\"utf-8\"", 
         "Accept: application/xml", 
         "Cache-Control: no-cache", 
         "Pragma: no-cache", 

         "Content-length: ".strlen($xml_post_string), 
        ); 

SOAP头是

<?xml version="1.0" encoding="utf-8"?> 
          <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://ws.mrted.com/"> 

    <soapenv:Header> 

     <wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> 

     <wsse:UsernameToken wsu:Id="UsernameToken-1"> 

      <wsse:Username>*********************:guest:FO</wsse:Username> 

      <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">guest</wsse:Password> 

      <wsu:Created>2012-07-09T11:35:20.019Z</wsu:Created> 

     </wsse:UsernameToken> 

     </wsse:Security> 

    </soapenv:Header> 

这我得到的是打印在浏览器卷曲响应后的反应 - -

<env:envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> 
    <env:header></env:header> 
    <env:body> 
    <ns2:getcriteriaresponse xmlns:ns2="http://ws.mrted.com/"> 
    <ns2:standardcriteriawithlovs>

    </ns2:standardcriteriawithlovs> 
    </ns2:getcriteriaresponse> 
    </env:body> 
    </env:envelope> 

这是肯定的，我得到的数据，但格式可能是错误的或我缺少的东西。

请提前。多谢。

$response2 = <<<EOF 
<env:envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> 
    <env:header></env:header> 
    <env:body> 
     <ns2:getcriteriaresponse xmlns:ns2="http://ws.mrted.com/">

      </ns2:standardcriteriawithlovs> 
     </ns2:getcriteriaresponse>

EOF; 

$parser = simplexml_load_string($response2); 
$parserEnv = $parser->children('env', true); 
$languages = $parserEnv->body->children('ns2', true) 
    ->getcriteriaresponse->children('ns2', true)

foreach($languages as $language) { 
    $label = (string) $language->label; 
    $value = (string) $language->value; 
    echo $label, ' => ', $value, PHP_EOL;
